李安民主任说，手机的广泛使用，使我们被罩在“电子雾〞中，无处躲避，而且这种电磁辐射无时无刻不在影响着我们的身体。当我们用手机打电话时，手机将音频信号通过转换器形成高频震荡的微波，然后通过天线以电磁波的形式发射出去，这时在手机附近就会产生较为强烈的电磁辐射。即使我们本人没有打电话，也难以防止不受辐射影响。一部手机就相当于一个小的微波发射器，微波对人体的损害是热损害。很多人都会有这种体会，打手机超过几分钟后，耳朵和脸部都会有发热的感觉。手机辐射尤其对人体含水多的组织大脑和眼睛损害的程度严重，全身组织大脑和眼睛的含水量最高的到达了７５％。另外，手机辐射频率在８９０——９００ＭＨｚ，辐射能比拟大。会对脑细胞产生高频震荡，轻那么影响细胞的正常工作，重那么造成脑细胞的变性坏死，确切地讲就是有个别的脑细胞就像被“烫熟了〞。长时间使用手机肯定会影响大脑的功能，造成记忆力减退、失眠，甚至会发生情绪的改变。个别人也可能因为神经细胞和神经胶质细胞的畸变形成恶性脑肿瘤。另外，眼球那么更容易吸收电磁波，并且其散热功能差，很容易引起白内障等疾病。
